NAME
    passwd - compute password hashes

SYNOPSIS
    openssl passwd [-crypt] [-1] [-apr1] [-salt string] [-in file] [-stdin]
    [-noverify] [-quiet] [-table] {password}

DESCRIPTION
    The passwd command computes the hash of a password typed at run-time or
    the hash of each password in a list. The password list is taken from
    the named file for option -in file, from stdin for option -stdin, or
    from the command line, or from the terminal otherwise. The Unix stan-
    dard algorithm crypt and the MD5-based BSD password algorithm 1 and its
    Apache variant apr1 are available.

OPTIONS
    -crypt
   Use the crypt algorithm (default).

    -1 Use the MD5 based BSD password algorithm 1.

    -apr1
   Use the apr1 algorithm (Apache variant of the BSD algorithm).

    -salt string
   Use the specified salt. When reading a password from the terminal,
   this implies -noverify.

    -in file
   Read passwords from file.

    -stdin
   Read passwords from stdin.

    -noverify
   Don't verify when reading a password from the terminal.

    -quiet
   Don't output warnings when passwords given at the command line are
   truncated.

    -table
   In the output list, prepend the cleartext password and a TAB char-
   acter to each password hash.

EXAMPLES
    openssl passwd -crypt -salt xx password prints xxj31ZMTZzkVA.

    openssl passwd -1 -salt xxxxxxxx password prints
    $1$xxxxxxxx$UYCIxa628.9qXjpQCjM4a..

    openssl passwd -apr1 -salt xxxxxxxx password prints $apr1$xxxxxxxx$dxH-
